'Game Of Thrones' Prequel Series Premieres Sunday On HBO

A new series brings dragons soaring above Westeros again.

The power of these flying serpents is in full display in the much-anticipated new series the "House of the Dragon", the prequel to "Game of Thrones".

For actor Matt Smith, these beasts weren't as dangerous as they look.

"It was a good laugh. It's like being on a big mechanical bull and they fire a load of wind and rain at you. You're quite high, about 20 foot in the air. And then someone's got a remove control and he's sort of like, leveling you around," said actor Matt Smith.

The House of the Dragon premieres on HBO this Sunday.
